VOSH Illinois first made glasses in the field in 2013 on a trip to Samapaita, Bolivia.

They made approximately 300 pairs of custom glasses in the field.

The lab encompassed 5 individuals.

One person pulled the lenses and marked them with a lensometer.

The second person centered the lenses for the patient’s PD and traced the frame shape onto the lens.

Third person used a belt sander with either 60 or 80 grit to grind the excess lens material down to within a couple of mm of the final size.

The fourth and fifth persons were both using a hand edger to take the lenses down to final size and mount them into the frame.

The glasses were then cleaned and dried before being dispensed.

The patients saw much better than they did with used recycled glasses.

The Rx range ran from +6.00 to -6.00 in spheres and also with -1.00 cylinders.

Far more plus lenses were used than minus.

On next trip they plan to take both -1.00 and -2.00 cylinders from +0.50 to +4.00

Please contact Dr. James Vaught for more information:

Updated COVID-19 and VOSH Humanitarian Clinics Advice

Due to an unprecedented surge in COVID-19 infections, a new variant that is more contagious, and these being early days in the vaccination distribution, VOSH/International DOES NOT recommend that chapters participate in domestic or international eye and vision clinics at this time.

We reiterate that at a time when the coronavirus continues to spread quickly in many parts of the world and vaccinations are not yet available to local populations, the risk of close contact with patients in a crowded outpatient environment remains high.

If a VOSH Chapter or VOSH volunteer chooses to hold a clinic against our best guidance, this is done at your own risk, by your own decision and should be in line with current local/national government rules.  VOSH/International would like to reiterate that safety for VOSH volunteers and our patients is of utmost importance and central to any decision-making process.

We have published our updated clinic guidelines with best practices to be observed in this new context.  You can download VOSH/International clinic guidelines here
